RADIATOR CONSTRUCTION Filed Nov. 4. 1929 y E" Wm Mu @i fmwumbZ/W ATTOFRN EYIS Patented Feb. 9, l9 32 UNITED STATES EARNEST L. WATSON, OF MILAN, MICHIGAN RADIATOR CONSTRUCTION Application filed November 4, 1929. Serial No. 404,754.

This invention relates generally to radiators and refers more particularly to those designed for use in buildings, dwellings and the like.

Une of the essential objects of the in- `vention is to provide a sectional radiator that simulates but can be manufactured more economically than the conventional form ot' cast iron radiator.

Another object is to provide a radiator of the type described in which (l) each header and intermediate tube of each radiator section has two complementary pressed or stamped metal parts suitably secured together, and (2) the sectional or two-part headers have tubular portions secured, preferably by welding, to opposite ends of the sectional or two-part tubes.

Another object is to provi-de a radiator of non-rusting metal that is lighter in weight than the conventional cast iron, that has a smooth and fine finish enabling it to be used in its own natural finish in a home, that may be easily and economically electroplated, and that has a much greater heating capacity than is possible through the conventional use of cast iron.

Another object is to provide a radiator' in which tubes of various lengths may be used depending upon the height of the radiator desired.

lith the above and other object-s in view the invention consists of certain novel features of construction, combinations and arrangements of parts that will be hereinafter more fully described, and particularly pointed out in the appended claims.

Referring now to the drawings, l is a radiator embodying my invention having parallelsheet metal radiator sections 2 and cast met-al supportinglegs 3. As shown, the radiator simulates the usual or conventional cast metal radiator, and the sections 2 receive the usual nipples 4; however, the sections 2 are formed of non-rusting metal such as brass or copper. Preferably each section 2 is identical in construction and comprises an upper and a lower header 5 and 6 respectively and intermediate tubes 7. Likewise the headers 5 and 6 are identical in construction and each comprises two complementary sections 8 and 9 of elongated pan like configuration opening toward each other and provided at the center thereof with aligned outwardly embossed circular portions 10 and 11 having aligned central open ings 12 and 13 respectively therein. As shown, the sections 8 and 9 have interlocking flanges 14 and 15 Welded together along one longitudinal and both transverse edges thereof and are provided at spaced points along the other longitudinal edge thereofv with inwardly extending substantially U- shaped depressions 16 havingr interlocking marginal flanges 17 and 18 respectively weldn ed together and providing laterally spaced short tubular portions 19. Preferably all of thetubes 7 are alike and each comprises 11 two complementary sections 20 and 21 respectively of channel configuration opening toward each other and having interlocking marginal flanges 22 and 23 respectively i along their longitudinal edges welded t0- gether. As shown, these tubes extend between and are'butt welded to the tubular portions 19 of the headers.

In the present instance cast metal tubular bodies 24 extend between the sections 8 and 9 of each header and are adapted to receive the usual screw nipples 4, while ferrules 25 of suitable material are used as reinforcements at the joints between the tubes 7 and headers 5 and 6. Preferably the bodies 24 are in alignment with the openings 12 and 13 and have the opposite ends thereof within and welded to the embossed portions 10 and 11 of said sections. In this connection it will be noted that these tubular bodies 24 form transverse braces or ties for the header sections and materially strengthen and reinforce the headers. As shown, each body 24 has right and left hand threads 26 and 27 respectively at opposite ends thereof for the reception of the usual nipples` 4 and is provided intermediate its ends with spaced openings 28 permitting the heatingmedium to circulate therethrough. The errules 25 are received within the tubes 7 and tubular por-l tions 19V of the headers and are welded together. i n Y In the process of construction, the header sections 8 and 9, tube sections 20 and'2l, cast metal bodies 24, legs 3, and ferrules 25 are separately formed, and in this connection it will be noted that one set of dies will suffice to make the sections Sand 9 of both headers 5 and 6, and that one set of dies will sufice tov make upk tube sections 2O and 21 respectively O various lengths. Tubularl bodies such as 24 are placed between and are welded to. the embossed portions 10 and 11 of the header sections and the latter arevthen secured together at the meeting .edgesthereoh preferably by being welded thereto. sections such `as 20 and 21 of the desired .length are secured together along their meeting edges, preferably by a welding operation, and after the ferrules 25 have been secured, preferably by a 'welding operation,

in the tubular portions 19 ofvv the headers, the Y tubes 7 are secured'to the tubular portions 19 of the headers by a butt welding operation. Nipples such as 4 are then used tosecure the desired number of finished radiator sections 2 in parallel relation, and legs such as 3 are secured, preferably by welding, to the lower headers of the end sections when radiators on legs are required. i

lThe proposed use of brass or copper will vprovide a non-rusting radiator of much greater heating capacity than is: possible through employment of cast iron, and its low cost of manufacture willpermit of its use in any home wherein cast ironradiatorsmay be specified.

Thus from the foregoing it will be apparent that a radiator constructed in accordance with my invention is simpler, lighter in weight, easier to handle and install, cheaper to manufacture, and is more eficient than the conventional cast metalV radiators of similar design or configuration. -i v Y While itis believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may bere- Ysai-d sectionsfbeingprovided at spaced points of their other longitudinal edges with aligned arched portions with flanges projecting inwardly from the edges of said arched portions, the opposed inner edges of the last mentioned flanges being securedy together whereby relatively vshort tubular portions are provided between said varched portions for attachmentto radiator tubes and the like.

2. In a radiator, aradiator section having Lipper and lowerheaders and intermediate tubes, each header being hollow and substantially rectangular in configuration, thelower header being provided in itsupper longitudinalv edge with spaced substantially U-shaped portions andV .provided between4 said U- shaped portions with relatively short tubular portions, the upper `header being provided at spaced points of its lower longitudinal edge withspaced arched portions and provided between said arched portions with relatively short tubular portions, opposite ends of the intermediate tubes aforesaid abutting and` securedto the tubular portions respectively of the, upper and lower headers. l

In testimony whereof I aiiix my signature.
